"600,0534 of March 1,1898., and more particuscribed in said application;

"rectly' into an active 'shuttle in box under the transferren ln our improvements as i described a magazineis provided having two residing at Worcester, in the county ofl/Vorces-v ter and State' of Massachusetts, have 'in-V vented certain new'and useful improvements nr'invention relates to automatic'weft-rel plemshing looms of the class shown and 'dey l'arly to the wet-replenishing loom shown and described in the United States Letters Patent No.` v805,1O9of November 21,1905, and to the Iilling-supply- 'mecha'nismv shown and deln said Patent No. 805,109 .is shown'and' described a magazine of the lilling-supply mechanism having a set of compartments 'comprising` two com partments, one on each side of the transferrerl and each compartment adapted to'parry a series of bobbins or filling-carriers which-,may

be transferred from a terminal position in the lower end of either of the compartments di-` the shuttleherein shown and sets of compartments 'comprising four compartments, two oneach side of the transferrer, each compartment ol' one set on the inner side of a compartment of the other set, and ythe filling-carriers of the two inner compartments overlying those in the two Outer compartments,` Witli thel terminalsot .the four compartments movable with the magazine under the transferrer ,in consecutive order, first the terminal of, an outer compartment, then the terminal Otan inner compartment,

i both on one side of the transterrer, then the `terminal of the other inner compartment and the terminal of the other outer compartment,

both on the opposite side of the transferrer.

Means are providedto retain any one ofl the terminalsm position under theV transfer rer when a 'transfer ot a bobbm or filling-carrier is to be made.

ln our improvements, as shown in the 5o `drawings and hereinafterdescribed, the transl'crrer is above a bob bin or llingcarrier when it is in a position to be transferred into a shut- The movement of the magazine when the l filling in the active shuttle is substantially eX- hausted places the terminal of one of the four Vcompartments under the'transferrer, which has a filling-carrier of the same'color as that inl the active shuttle, preparatory to the transfer ofthe filling into the active shuttle.

llthen either of the inner compartments of the magazmeis 1n a position Jfor a transfer of a illing-carrier, such filling-carrier is directly under the transferrer; but as the lilling-carriers ol: the inner compartments overlie the lling-carriers of the outer compartments in lorder to transfer a filling-carrier from one of the outer compartments when its terminal is in position under the transferrer it is necessary to move away the overly-ing filling-car'- riers in the inner compartment at the time the maggazine moves to bring the terminal of one of the outer compartments into position. The transferrer is then in such. a position that it will movethe overlying lilling-carriers out of the way and uncover the iilling-carrier in the outercompartment at the terminal thereof and ailow the transferrer to act directly to transfer' said `tilliiig-carrier into the shuttle.

ln order to obtainV the result above reerred to, the guideway te-the terminal of each inner compartment is turned downward at an'angle to the guideway of the filling-carriers above the terminal, thus making the illing-carrier at the terminal of the guideway at a greater distance from the center of movey ment of the magazine than the filling-carrier just above it, and as there is only sufficient room whenthe transferrer is in its normal position to allow the filling-carrier at the terminal of an in ner compartment to move under the transferrer it follows that i1" the magazine moves to place theterminal of one of the outer compartments under the transferrer that the filling-carrier of an inner compartment next above the 'lilli11g-carrier at the terminal which is nearer the center of movement of the magazine will as the magazine is -moved come in contact with the transferrer and loe pushed up or raised to uncover the @ling-carrier at the terminal of an outer coml into the shuttle.

After the transferrerd'has returned to its normal position it will still act to retain the filling-carriers of an inner compartment in their raised position; but if the magazine is moved into a position to transfer the rillingcarrier from the terminal of an inner compartment then the raised fillingvcarriers will resume their normal position adjacent to the filling-carrier at the terminal.-

After the filling-carrier is transferred from the terminal of an ,inner compartment the transferrer is returned to its normal position, which position prevents the filling-carrier adjacent to the transferred fillingcarrier from dropping into its terminal position. To en able said filling-carrier to drop into its normal position, an additional upward movement is given to the transferrer sufficient to allow said filling-carrlier to pass under the transferrer and fall into its terminal position, and the remaining superposed filling-carriers follow after and present an unbroken series of filling-carriers. As soon as the lowest filling-carrier reaches its terminal position the transferrer moves down to its normal position for its next movement when required ing-carrier.

We have only shown in the drawings a detached ortion of the filling-supply mechanism emllodying ourimprovements. It will be understood that the mechanism for moving the magazine according to the requirements of the supply of fresh filling may be of any suitable construction and operation.

Referring to the drawings, Figure 1 is a vertical sectional view through the magazine, taken at a point indicated by line 1 1, Fig. 2, looking in the direction of arrow a, same figure, and shows also the outside of a loomframe and parts of the weft replenishing operating mech anism combined therewith.

Fig. 2 is a front edge view of the magazine;

looking in the vdirection of Yarrow' b, Fig. 1. @nly a: single bobbm r iilhng-carr1er1s shown in this figure. Fig. 3 shows the magaaine shown in F ig. 1 in a different position and with the transferrer in the same normal position. Fig. Zicorresponds to Fig. 3, but

. shows the transferrer in its raised position.

y in the accompanying drawings, 1 is the loom side; 2, the bottom cream shaft; 3, the lcranl-shaft; 4, Athe breastebeam; 5, the

lay-beam', and c the stationary shuttle-box thereon. A ,y

7 is the loom-arch. 8 is a stand, secured in this instance to the.loomarch 7 and to the frame 1 at the end of the breast-beam 4.

` The stand 8 has secured thereto a stud V9,-

on which is looselymounted inthis instahcea sleeve 10. Fast .on the inner end ofthe sleeve 10 is the hub 11" of a plate ilgforming inthis instance the innerend or head ofthe.

to transfer another fdlmagazine. Also fast on the sleeve 1('),`near the outer end thereof, is the hub 12 of a plate 12, forming the outer end or head of the mag partments 14 and 14.

The outer compartment 14 and the inner compartment are located on one side of the pivotal support of the magazine and on one side of the transferrer, and the outer compartment 14 andthe inner compartment 15" are located on the oppositeside of the pivotal support of the magazine and on the opposite side of the transferrer.

The bobbins or iillingcarriers 13, carrying, preferably, four different colors of filling corresponding to the colors on the {idling-carr riers in the four shuttles of the four drops'huttle boxes at the opposite end of the loom, (not shown,) are placed in the compartments or guideways 14 14', 15 and 15', through their upper open ends, and drop down by gravi? y to their lower open ends, where the lowest bobbinor filling-carrier in each compartment is yieldingly held in its terminal position, in this instance by a spring-blade 16, attached to the inside head 11 of the magazine for the head of the bobbin, andthe spring-blade 17, l

attached to the outside head 12 of the magazine for the tip of the bobbin. (See Fig. 2.)

The terminal point or discharging end of the fourcompartments or guideways 14 14'.,-

15 and 15 are located in* this instance side by side, as shown inftle drawings The terminal or dischar in"`i""en'dof thev two inner guideways 15 an lffextends at an angle to the main portion of the g-uideways, as shown,

for the reception of the vlowest filling-carrier in each-compartment, so that the distance of the two lowest fillin -carriers in the two guideways 15 and 15' wi l be farther from the axis or pivot of the magazine than the distance of the filling-carriers above said lowest filling carriers', as will be readily seen by .referring to Fig.' 3.

The magazine has a rocking motion Gorhmunicated thereto, in this instance through an arm 18, link 19, anglelever,20,pivoted-on ay stud 20', and connector 2 1 to mechanism v which may 'be connected with or governed by the shifting. or drop shuttle boxes at the opposite end Aof the loom to bringv the terminal position of any one of the compartments,le

14', 15and 15 over the stationaryushuttle" box lllingrarrier the lower M ferrer.

The transferrer 22- (see is secured tothe transferrer-arm 23, pivotally mounted 5 on a s tud 24and having connected there-- with 'a spring -25 in the usual way'. The transferrer 22 is operatedin the usual and well-known way at the required time to move down and engage the head andtip of the iillro ingscarrier 13, 4which extends directly under it to transfer the iilling-carrier into the shuttle in the shuttlebox 6 under the magazine. The transferrer 22 extends between the two sets of compartments o f the magazine with t5 its engaging ends just above the lowest filling-carrier in the inner compartment 15er 15 which has its terminal yposition in lino with the stationary shuttle-box 6, (see Fig.

3,) so that as 4the ma azine moves or rocks to carry the terminal o one or the other of the inner compartments 15 or 1 5 inline with the 'shuttle-box 6 the engaging end of the transferrer will just pass overthe tops of the lowest filling-carriersy `in said two compartments. z 5 In case of an additional movement of the magazine, to place the terminal of either of .the outer com artments 14 or 14: in line with the shutt e-box 6, with the lowest fill-- ing-carrier in said compartment under the "transferrer, the transferrer will engage with the filling-carrier in one of the inner compartments next above the-lowest fil -carf rier in said compartment and nearer to the axis of the magazine to push up or raise the 3 5 seriesof filling-carriers in said compartment,

as shown in Fig. 1, so as to uncover the lowest idling-carrier in one of the outer compartments and allow the transferrer to engage therewith and transfer it into the stationary shuttlebox' 6.

After the filling-carriers have been moved or raised up by the transferrer, as above described and shown in Fig. 1, in order to ref turn to their normal position, as shown in Fig.` 3, the magazine must be moved to bring the terminal of one of the inner compartmentsinto Vits lowest position, as shown in Fig. d

We will now describe the mechanismshown 'in the drawings for giving to the transferrer the additional upward movement above its normal position to allow the illing-carrier in an inner compartment 15 orv 15- to drop un der the transferrer and move into its termi- 5 5 nal position after the Iillinwcarrier at the terminal has been transferrer n the bottom shaft 2 'is'fast a cam 26, (see Fig. 1,) on the.

periphery'of which travels a rollA 2 7 on a pin 28,* in one arm of-an angle-lever 29, pivoted on a'stud 30 on a stand'Sl., secured to the loom-frame. The' other arm of the angle-lever 2.-l has pivotally attached thereto the lower `eind of a connector 32;,having a slotted open-` ing 32in its upper end to receive a pin 3 3, o which can move freely up and down m said lewin slotted ope and-isaettacliedto the Farm 23 on'the transforment' 23.V A spri 26 acts to lree the roll 42"? in vcontact with the cam- .die the cam 2e rotates `the roll 2'2" will travel on the lowerIart of the.cam, al- 7o the roll 27 and te 4lower arm of the' angleever 29 to move nearer'the axis` of tlc cam and at the same time allow the opposite' arm of the an lle-lever 29 and 4the connector to be raised land also allowthespring 25. 7 5' to raise the transferrer-arm 23 through 'the pin 33, moving in the opening 32' to carry the transferrer 22 aboveits-normal position or into the position shown in Fig. 4, inwhich position the iilling-carriers -in 'an innerv coml '8o partaient c1115 are free to|` ass by 'the' lower engaging ends of thetrans errer and to drop down. into their normal positions, as shown in llig'. a. The continued rotation-of the salu2@ and the passing of the roll 27 on; 85

lto .the higher part of the cam, through the angle-lever 29 and the connector 32,engag ing the pin 33,'movesdown the transferrer arm 23 of the transferrer 22 into its normal position. (Shown in Figs; 1 and' 3.) The 9o cam 26is oreferably so shaped that the movement of t e angle-lever 29 andthe connector 32 occurs at .every second movement of the lay to allow the transferrer to be raised l above its normal position; but no effect is produced upon the filling-carriers in the ma azine until the transferrerlis actuated in t 1e usual manner to transfer a filling-carrier, during which operation the pin 33 on the transferrer-arm will be free to move downroo wardly in the slot 32 of the connector 32.(l

lt will thus be seen that while` this additional upward movement andthe return to its normal position of `the transferrer takes place regularly at everysecond movement ofthe -lay it in no way interferes with the usual movement of' the transferrer to transfer a lilling-carrier into a shuttle, accordingto the indications of the mechanism controlling the movement of the transferrer.

It will be understood that the details of construction of our improvements may be varied if desired.

Having thus described our invention, what we el aim as new, and desire to secure by L'et- 1:15 lters Patent, is-- f 1 i.

l. ln a weft-replenishing loom, a magazine comprisingtwo. sets of compartments' or guideways, an ou ter set', and aninner overlaying set, the terminals of? the inner set inter izo posed between theterminals of the outer set, and the terminals of the inner set being turned downward atv a'n angle to the main vportion of. the compartment or guideway.

2. in a weft-replenishingloom, a' pivoted 12 5 magazine having two sets of guidewavs or compartments for iilling-carriers, each set A having two guideways or compartments, and the inner set over-laying the outer set, with its two tei-mirarla interposed between the two 13o of 'the outer set7 ancl all four terminals substantially the same distance from f the oi'the ma azine.
